To ad whom it may concern,.-

. B e it. knownthat I, CHARLES H. BoEoK, a citizen ol` lie United States, residin at Jackson, ir the c'ounty of Jackson an State of ,Michigan have invented certain new and useful I improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thev same. v

This invention relates to domestic refrigerators. Y I t provides a practicable and efficient metal construction therefor, princi ally of sheet metal, combining lightness o vweight and simplicity of Structure with strength and durability.- The parts arevingeniously constructed and arranged so as to be readily assembled and are firmly secured to ether simplyby longbolts extending from te top to the bottom of the body.k The interior lchambers of the refrigerator are well protec'ted froml the influences of outside temperature, while the arrangement of the air-passages between the ice-chest and provisionchamber is such as to maintain aneffective circulation of cold-air currents about the provisions. I` Important features of improvement pertain also to the various mechanical a pointments, the ice-tray, the drip-pipe, t e provision-shelves, and the supportingbase, all of which are of novel construction and contribute to the general efficiency and yexcellence of the refrigerator.

The accompanyin drawings, which are to be taken as a part of this specification, illustrate one preferred form of embodiment of the invention, the 'details of which, however,

'may be modified' in various ways, so thatj without restricting myself to the specific embodiment shown the invention will be fully described with reference to said dra'win and then particularly pointed out and defined in the annexed claims. f

.The refrigerator-body, formed in upper.

and lower sections, comprises concentric outer and inner casin s of sheet metal, prefhese casings leave beerably sheet-steel.

tween them ank annular dead-air s ace surrounding the internal chambers of t e refrigg erator. A denotes a sheet-metal base. and C designate the outer. and inner casings of the lower section; D and E, the outer and inner casings of the upper section. The bottom of the outer casing B fits snuglywithin the fianged periphery a of the bottom plate A and is supported thereby. Restinglu on said bottom plate is a ring F., upon w ic is supported a plate G, said rin and plate being likewise .of sheet metal. T e plate G constitutes the bottom of the vprovision-chamber contained within the lower section. Said late G has drawn thereon an annular depending shoulder g, with a peripheralrflange g', which fits within the outer casing B; Said shoulder g incloses the upper` edgel of the ring F and is itself fitted within the lower end of the inner casin C, which rests upon the ange g. Thust e casing C, plate G, and ring-E are pro rly centered and held rigidly in correct re ation. Resting uponthe u per endyof the inner casing Cisa sheet-meta plate H.

This constitutes the .top of the provision- IOO chamber and' the bottom ofthe ice-chest, l

which is contained within the upper section.

Said plate H has drawn thereon an annular yshoulder h, with an outer flange h', which The upper inner casing E rests upon the flange and hasits lower end fitted within the shoulder h2. third concentric casing or cylinder I, providing an annular air-.flue around the icechest, or-between I and E. This innermost casing I rests upon said plate H and hasits lower end fitted within the shoulder h. Thus the casings C, E,q and :I are properly centered and .supported by the plate H. These parts H, ligand I should be zinc-plated or galvanized to .prevent corrosion. The innermost casing I has a top flange i shown fitting within the. inner flange k. of the top ring lK and closing the aforesaid air-flue at the top, and

said flan e i is shown .provided with handles i for-lifting out this cylinder I from Itime to time for cleansing The handles fi consist of Ugshaped bars whose legs depend through apertures in the flange i, the lower extremities of said legs being formed .with knobs, as shown in Fig.- 7, to prevent-the handles from beindetached, while yet allowing them tol belfted for Ataking out the cylinder I. When inzplace, the handles i drop down through,4 the. flange i out of ,the way. Thelowerrend ofthe upper outer casing D is fitted within. theupper endof the lower outer casing. B andfhas an annular bead or corrugation d. resting upon the upper edge of B, thus supe portingand centering D. The whole outer casing, -B D is preferably, though not essen-l tially, made .in up er and lower sections, Ias shown .in view of tfie doorway construction in the lower section of therefrigerator, as hereinafter explained. Annular sheet-metal bands .or ringsJ, which .may be flat or other orna'.- mental shape, but preferably concave or semicireular 'in crossfsection, surround the body, strengthening the same, making it rigid and preventing -rnarring or denting in transportation, as .well as coveringthe joints and ornamenting the structure. One of these bands islocated around the bottom between the.. flange a of A and an annular bead b on B. Another is disposedfaround the joint between the upper and lower sec tions, beingv secured between the beads b.

and d on B and D, respectively. A third one isplaced around thisJv top between ,an annu-- lar bead d on D and a depending' flange. 7c,

on the top ring K. This top ring issecured upon the upper ends. of casinvs D and E, havinginner and outer flanges l? and kf .depending around -the upper peripheries. ofsgd vcasings, and it,closes the annularhollowrefrigrerator-walls or dead-.air space at the top. t is secured in place by screwing it to liners k2 Within the casing E is al or small angle-shaped metal pieces riveted orl otherwise attached to the casing E. The

partsthus constructed'and assembled are.'

rigidly secured together bylo bolts or rods L, connecting the to ring I and bottom plate A and extending ljongitudinally through the hollow refrigerator-walls, being )assed through appro riate'apertures in the anges ofthe plates and G.

It is observed that the internal chambers of the refrigerator are surrounded by the hollow refrigerator-walls or aforesaid. annular dead-airgs e .between Ethe-outer;and inner Casimgs?, W 1' e. a.dead.ai-r s are isalso formed belowthe. provision-.cham er ywithin the ring F. All ofsuch deadqair spaces, as welles those in the coverand front door, are preferably lined interiorly with ,asbestosfcloth,. (dee noted by the letter M,) which isforfthe wellunderstood purpose. of increasingthebonconductivity of the wallsiand. insuring `the interior of the refrigerator from theinfluence of outside. temperature.

A removabletof cover N Closes the. icechest, fitting tight y within the topfring-.K and resting upon(the-annular` seatafforded by the. flange i omthe innermostl casing IA This top2 vcover-is hnllow and lined with .asbestes-cloth, as aforesaid.` Itgmay consist of sheet-metal plates, theup erone n ofwhich is. convex and .has a. perip ieral flange, while the lower one n has. an upset flange a2, (which .fitswithincthe topI ring K,) and Aarecurved peripheral flangecn embracing thev peripheryorflange offri, and thusformi-ng al thin flange for the. whole cover, rests upon the to ringy when the .cover isdown. The lower p aten may be of zinc orugalvan-l ized metal. The top cover-is vshown hinged at n* -to the top ring K and..p.1`o.vided witha handle, 71,5. The butts .or leaves .of ,thel hinges are secured to the sheet-metal coyerand rm f by screwing or bolting them to concealed linersnf or metal pieeesunderlthe surface of said cover and ring, and the bandlen isnttached in like manner. Itinay beremarked here lthat such liners are, employed throughoutthe. structure for-fastening to theslleet metal all thedoorand other :fitti s or mount'- ings comprising the .hin es, loc handles, @ce` A stop or rest 'a7 is. ikewise secured ,on the Ahingedside ofthe coverto hold it-up when opened.

The doorway construction at the front of the provision-chamber is asfollows: Around the opening or doorwaythe .inner casing C is fla ed outwardly atc,while the outercas= ingn is flanged inwardl .at b?, theflangebf-fittingsnuglyaround theI anges and projecting beyond the same andmeanged, so ,astoffit tightly to the interior Walls. In viewof vthis construction it isdesirablato make theeaa ings B -and vC eachof. two parti-'cylindrical parts, which areshownm Fig. of .theidraiv- IOC lugs Secured together .alongL thalengitudinal x 3o seams b3 b3 and c c". The door Q fits tightly within the doorway. -It is hollow and asbestos-lined like the other parts. It comprises an inner plate q and an outer plate q l oth of sheet metal. The inner plate is ilanged outwardly at g2 and terminates in a peripheral flan e g3, which is embraced by the recurved ange q* of the outer plate.

.The hinges g5 and lock members q are attached to the sheet-metal parts by means of concealed liners q7, as aforesaid..

I make no specific claim herein to the construction of the door Q per se, since the same forms the subject-matter of an additional ap,- plication for improvements in refrigeratordoors, iiled December 8, 1905', v'Serial No. 290,941. s

The-bottom late H of the ice-chest slants downwardly al around from the periphery to the center, where an aperture is provided into a medial dri -pi e R. Thisv drip-pipe e has its upper end tte over a depending. tu

or boss 1" on the bottom of the plateH and extends downward through the bottom 'of the refrigerator. It has a shoulder r vresting upon `the plate G. Surrounding the lower reduced part`1'2 'ofthe'pipe is a sleevera, interposed between A and G. The lower end of the pipe beneath the bottom of the refrigerator 1s threaded. and has anut or' nipple r4 screwed thereon, to which is attached a dri cup 1'5. By virtue ofthe sleeve r3, if the nipp e r* 1s screwed u tight it is impossible to bend or press the p ates Aand G together. Said sleeve also supports the center of the plate G against the weight of the provision-shelves on the drip-pipe. The plate H has large op.

' eningsuh therein to allow the cold airfrom the ice to fall down into the provision-chamber below. Theedges ofthe plate are flanged upward around said openings to prevent the dripping of water into the provision-chamber.-

The` flange hy o f H between E and I is, provided with aperturesto allow-the ascentl of the warmer currents from the provisionchamber, which pass upward through the annular flue surrounding the ice-chest andl enter the latter through an annular series. of apertures i2 at the top. Thus an effective circulation and constant descent of fresh coldair currents upon the provisions is maintained and there can be no moisture in the provision-chamber.- Matches may be kept dry there, if desired. The ice is supported upon anice-tray S. As shown, this comprises corrugated metal sheets s secured upon ars s of angle-iron, makin a very strong rigid support for the ice.- he ends'of the bars s are bent down to form supportinglegs s2, resting upon the plate H, and under said bars there 1s attached a late sa large,-

cold air from the ice naturally passes down around over the plate 'sa and through the said openings into the provision-chamber.

Thel drip pipe R furnishes a convenient meansforsupporting the provision-shelves,

of which there may be one ormore or any "a cross-piece or frame U, which is -revo ubly mounted on the dri -pipe and can also be raised and lowered, eing su orted upon a'.

vertically-adjustable clamp This clamp may be integral; but, Vas shown in detail in Figs. y11 yand '12,' it preferably comprises. two separable parts, .whereof one has atongue v engaging in a slot or Vopening in the other atone side of the drip-pipe, while both parts are clamped together. on the drip-pipey 'a thumb-screw v engaging lthrough t flanges at the opposite side of the drip-pipe. This `allows 'the clamp to be readily applied The frame or crosspiece U comprises two metal'strips or lates u, secured flatwise--together and me iall formed into a sleeve or hub to loosely 1nclose the drip-pipe and having opp'ositely angled or bent ends a', between which longitudinally-disposed rods u2 are supported, one at each side of the drip-pipe, and

The refrigerator-body is supported by a'l metal trusswork cornprlsingv cross bars or ystrips W, attached \to the bottom of the re frigerator andbe'nt downward and braced to l provide the `supporting-legs w, which are mounted on rollers or casters. -To these legs are attached sheetmetal stoveleg-shaped legs w', which cover the trusswork beneath and produce an ornamental 'l effectj. The

bolts orvrodsL are'desirably. insertedthrough' 'the bars Wenas well as through the bottom The construction and arran ementof the several sections and parts, as we las the novel accessory features, are applicable also to square or pol gonal refrigerators, asbefore Stated. In igs. 13 and 14 I show a rio-id Asheet-metal corner construction especially adapted for such square or angular bodies, either for refri erators or other structures. The sheet-meta part X is shown formed into parti-cylindrical shape with its ends flanged or bent inward, as at to a common point and reflanged outward, as at m2, providing slots or seats between and m2, in `which the sides Y and Z may be tightly fitted. The flanged fparts may be joined at This feature orms the subject-matter of my pending application for Corner construction for sheet-metal bodies, filed April 3, 1905, Serial No. 253,543. i

The construction described rovides an ideal sheet-metal refrigerator wiiich `is light and convenient to move around, artistic as a household article, durable, and absolutely sanitary, being fireproof and disease-proof and characterized by cleanliness, in all of which respects it is far superior to refrigerators constructed of wood, indurated fiber,.&c. Furthermore, there is nothing to swell, warp,-

or shrink. The refrigerator is also economical and eHects a saving of ice by virtue of the construction and arrangement of the airs aces and the non-conductivity. Food and ainties may'be preserved in purit and freshness. rIhey will never taste of t e icebox, for the refrigerator is so constructed that all chance fortaste, odor, or other unsanitary condition has been eliminated. In

the cylindrical form there are no corners to wie out to the annoyance of the tidy housew1 e.
